Cold case - Sexual assault, slaying still beckon 48 years later

Marta Santa Cruz was last seen cashing a paycheck on F Street in Northwest D.C. on July 1, 1961. Three days later, a couple of teenage boys found her naked body halfway submerged in a creek 15 miles away in Springfield.

Cruz was only 24. Her roommate told police what Cruz was wearing when she left the house on Columbia Road the day she disappeared: a greenish-blue two-piece dress and a sleeveless blouse. She hailed a cab around 10 a.m.
